No. He is using a standalone system for the injectors and other stuff.

I'm gonna try to get a full season out of this motor and with my schedule this year I'll probably have at least 130 plus passes like last year and very few miles on the street again. I'm gonna limit my boost to about 15 lbs with my new setup.

15 psi on the stock motor?

Yep, should be pretty close to that. I'll know pretty quick once I get it back on the dyno next weekend and then to the track on the 10th of march. Ran 11-12 lbs almost all last year.

Are you making 600+rwhp through stock cats?

I think 700whp is totally do-able provided you have a low DCR, good fuel (e85 or high octane gas, or plenty of water injection), and run a little fat too. And definitely headers. It seems all the c7's that are making big power have a real aggressive cam on them which lowers the DCR. At least the few that seem to have survived. Also depends on how hard you beat the car (thermal load intensity).
